VEHICLE-FRAME.

Specification of Letters Patent.

Patented Jan. 25, 1916.

1 b all whom it may concern Be it known that I, DONALD M. FERGUSON, acitizen of the United States of America, residing at Detroit, in thecounty of Wayne and State of Michigan, have invented certain new anduseful Improvements in Vehicle-Frames, of which the following is aspecification, reference being had therein to the accompanying drawings.

The invention relates to vehicle frames of that type in which the sidesills are connected to spring arm extensions, forming the resilientattachment to the axles.

It is the object of the present invention to simplify the construction,as hereinafter described.

In the drawings: Figure 1 is a perspective view of the end portion ofthe side sill; Fig. 2 is a similar View of the spring for engagementwith the side sill; Fig. 3 is a side elevation showing these parts in assembled relation; and Fig. 4. is a plan view thereof.

A is one of the side sills of a motor vehicle frame formed of a channelbar, and B is a spring arm forming an extension of said side sill andcomposed of a plurality of leaves. Heretofore it has been customary toattach the spring arm to the sill by an offset relation of the one withrespect to the other, the parts being secured by clips. My im provedconstruction is simplified and is more compact by placing the end of thespring arm within the channel of the sill, so that the two members arearranged in the same plane and in alinement with each other.

To secure the parts in the relation just de scribed, the end portion ofthe side sill is provided with a longitudinal slit C extending centrallyof the web thereof, and preferably terminating in a round aperture D atits inner end. This will permit of the springing of the top and bottomflanges E and F of the sill, so that they may be clamped down upon thespring arm B when arranged in the channel thereof. Thus by the use ofsuitable clips, such as G, the parts may be firmly clamped together, asshown in Fig. 3.

The clamping portion of the sill is preferably arranged adjacent to thecross member H of the frame, which latter also engages the channel ofthe sill and preferably abuts against the ends of the springs.

What I claim as my invention is 1. In a vehicle frame, the combinationwith a side sill of channel section, of a cross member engaging thechannel of said sill, an extension of said sill beyond said cross memberhaving its web portion slitted, a leaf spring arm inserted in the end ofthe channel abutting against said cross member, and clamping means forthe channel upon said spring arm.

2. In a vehicle frame, the combination of a sill of channel sectionhaving the cue portion of its connecting web slitted, a spring armengaging within the end of said sill, a bolt passing through the flangesof the sill and through said arm, and a member clamping the flanges ofthe sill against said arm, having a portion extending across the openside of the channel.

In testimony whereof I affix my signature in presence of two witnesses.
